Agree, but it could still be the N55 yet in a different state of tune. The 640, for instance, has a 315hp version of the N55 if memory serves. I figure, at least, they'll be putting that into the 3/4 series as soon as they get it certified.

yup

its called the n55hf. its in the 740, and the 135 coupe and m135 f20 as well

one would assume if they followed the new naming scheme, that we'll get the n55 in the 435i, the n55hf in the m435 if they release it (to replace 335is) and that will be that.

they know they will sell, and its simple. i'm going to figure this simplest explanation is the most likely occams razor and all.
